Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Apple Chutney
Ingredients
Directions
Make the chutney
Break apples into a preserving pan and add quartered apples.
Chop onions and add to the pan with all other ingredients except sugar.
Boil slowly until the mixture softens and becomes a pulp.
Rub the mixture through a coarse sieve and stir well.
If too hot, add finely chopped raisins when cold.
Adjust vinegar quantity for desired thickness.
Rest and bottle
Let it sit for a day before bottling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Break down into pulp, giving the chutney its body and thickness.
- Onions
- Add savoury bulk and aroma as they soften during slow boiling.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the chutney.
- Sugar
- Adds sweetness that balances the acidity and the heat of the spice.
- Cayenne pepper
- Provides heat and a sharp, spicy edge to the chutney.
The step that matters
Boil slowly until the mixture becomes a pulp. Slow boiling lets the apples and onions break down evenly without scorching on the base of the pan. Too fast a boil can burn the sugar and leave an uneven texture. Pectin in the apples helps the mixture thicken as it reduces.
Swap the raisin
The recipe marks raisin as optional. How well each one fits the dish's main ingredients (apple, onion, vinegar, sugar, pepper, garlic):
- Plumfits better
- Mangofits better
- Cherryfits better
- Raisinthe original
Fit is the average pairing score against apple, onion, vinegar, sugar, pepper, garlic. Candidates are from the same food group and used in at least 100 recipes.
